it could be Madonna as you wouldn't expect it to be her. And I think she has self esteem issues that make her go for abusive men. Probably stemming from her father. I have one story which I totally believe as true. A friend of mine was a showbiz columnist for a major UK paper but now based in Manhattan. Anyway, when Madge and Guy first started dating, my friend attended a big showbiz party in London, in which they were guests. Apparently Madonna was totally the subserviant one to Guy, he spoke to her like shit, she followed him around, he humiliated her in front of others. She ran into the toilets and locked the door, threatening to kill herself. She eventually got talked round to come out but was really crying. All the showbiz hacks know about this but would never report it in the papers as Madonna is such a big name and they don't want to have to prove it or be sued. They get plenty of publicity/money from her so they wouldn't want to alienate their cash cow or her fans.
I got told that there is so much stuff my friend has seen in showbiz circles that cannot be printed. That's how they get round it by doing blinds. Most of them are true.
